The adhesive can be used in solvent of ethyl acetate, acetone, methyl ethyl ketone, etc. It is recommended to use ethyl acetate. When the composite film with high quality requirements is manufactured, the water content of the solvent shall not exceed 0.03% and the alcohol content shall not exceed 0.02%.
Method of application:
Blend: 5 YH-9066A with 1 YH-9066B.
Dilution: Firstly add ethyl acetate to the main agent, stir thoroughly, and then add curing agent. The curing agent must be poured out, or reserve a small amount ethyl acetate to wash it out then stir thoroughly.
Coating method: It can be applied to the coating of any smooth roller and mesh roller.
Working concentration: Generally recommend to use the concentration of 20-40%, the best use of the concentration is 30%. Coating amount is between 2.5-4.0g /m 2.
Dry: There must be sufficient air volume, speed and temperature. Temperature control from the inlet to outlet should at 50-60 ℃, 60-70 ° C and 70-80 ° C.
Laminating: Under the condition that the roller does not damage the film, the pressure and temperature of the composite roller should be increased as much as possible. The temperature is generally controlled at 50-80 ° C. Films that are susceptible to temperature are used at 50-60 ℃, and other films can be used at 70-80 ℃.
Solidification: At the temperature 50±5 ℃ , maturing period is 48-72 hours.
Main agent 20kg/ barrel, Curing agent 4kg/barrel.
Storage:
This product should be stored in a cool and dry place, the main agent is valid for 1 year, the curing agent is valid for 10 months.
